Ok,
This one has me baffled.

This is on my 1990 500 SKS. The master cylinder does not match the part break down that I can find. The master does have a brake lock or emergency brake.

The one on my sled looks like my 1989, but has a round level "window", which is just vibrating around, so all the fluid has come out. The brakes kinda work at slow speeds, so I was looking to replace the gasket "o ring", but can't find it anywhere listed in the parts list.

Not sure if this was changed, and not a polaris deal, or what.

Thought I would seal it and then bleed the brakes.

Any advice on how how to fix this, or where I can get parts.

Thanks
Bob

Is yours the small master cylinder? I have two extra ones (both work but I have been switching over to the 95 style chaincase and brake systems on my older sleds) that I will probably not ever use and would be happy to ship you one if you'd cover the shipping cost.

Cool,
The master cylinder on my '90 SKS is bigger than the one on my '89 400, and has a parking brake lever. I would be happy to cover the shipping, and appreciate your offer, Send me a private message, and I can send you my address and can send money via paypal or mail payment.

Thanks,
Bob
